GRAIN-SAMPLER SPECIFICATION forming part of Letters Patent No. 399,687, dated March 19, 1889.

Application iiled March l, 1888. Serial No. 265,879. (No model.)

To @ZZ whom, it 71mg/ concern:

Be it known that I, BENJAMIN FRANKLIN MORNINGSTAR, ot Brooklyn, Kings county, in the State of New York, have invented a certain new and Improved Sample-Trier, of which the following is a specification.

My instrument may be used in sampling liquids of all kinds. It may also be used with success in sampling loose material ot' various kinds-any kind in which the grains are small, and which is inclosed in wooden boxes or barrels. I will describe it as applied to sampling wine or analogous liquids contained in barrels or tierces. I employ an auger or boring-bit with a peculiar tubular shank open along one side. lVithin the tubular shank is inclosed a tight-iitting smaller tube correspondingly open along one side and provided with means ior partially turning it. lYhen the interior tube is turned in pos-ition relaiively to the outer tube, so that the openings coincide, material may be taken in or let out. lVhen it is turned in another position, the opening is closed. An end plug is provided to facilitate the removal ot' liquid contents after the withdrawal of the filled instrument from a barrel or other package in which it had been inserted.

'lhe accompanying drawings form a part/of this specification and represent what I consider the best means of carrying out the invention. v

Figure l is an elevation. Figs. 2 and 3 are cross-sections on the line :rin Fig. l. Fig. 2 shows the device open and Fig. 8 shows the device closed. Fig. al. is a central longitudinal section 5 and Fig. 5 is a corresponding section ot the upper end with the instrument inverted, and with the plug removed to empty the contents through the end..

Similar letters of reference indicate like parts in all the figures where they appear.

A is a boring-bit of any ordinary or suitable character adapted to bore a smooth hole in wood or analogous material, say, threefourths of an inch in diameter.

Instead of an ordinary solid shank of small diameter, I provide a tubular shank, B, open along one side, b. It is nearly as large as the bit A. IVhen by strongly turning the instrument by its handle O the bit A has produced a hole in the barrel, (not shown,) the tubular shank B b maybe easily inserted by a simple thrusting motion and as easily withdrawn. A partial turning motion of the entire instrument while the tubular shank is properly inserted aids to ll its interior if the material be loose.

D is an internal tube having an open side, d. The interior of B is smooth and true. The exterior of D is smooth andtrue and of the exact size to lit tightly and easily within B, and these parts are applied together, with a smaller part of D extended out through the upper end of B and carrying a b tton, D', which allows D to be readily turned when required. A stop-pin inserted in D, as shown by D2, matches into recesses provided for it in B, and prevents D from being ever turned too tar.

G is an axial screw-plug controlling an opening in the upper or outer end oi' D.

D is contracted in diameter at each end, and is held in corresponding small holes in the ends ot' the hollow shank B, thus reducing the `friction which opposes the turning of D to an almost inappreciable amount.

In the use of the device it will usually be applied from above and used to bore a hole and abstract a sample on the upper side. It' the material be smooth, round, or approximately round grains, as wheat or rice, it will readily enter the shank when the interior tube, D CZ, is turned in the position tov allow it, but will also escape readily when the instrument is drawn upward. This is especially the ease if the contents of the barrel or other package be liquid. To avoid all difculty, I turn the interior tube, D (il, into coincidence with the hollow shank B b prior to the boring, and keep.

it so during the first part of the period while the device is fully inserted; but before drawing it up I turn the knob or button D', thus turning the interior tube, D d, as far as it is allowed to turn. After it is thus iilled and withdrawn, I take out the small plug Gr and invert the instrument over any suitable dish, into which the contents of the instrument will tlow and may be examined at leisure.

Modifications may be made without departing from the principle or sacriiicing the advantages of the invention. The screw or other IOO boring-bit A may be shorter. It is suiioient that it be of such length as will bore through the staves or head of the thickest barrel or case.

Parts of the invention can be used Without the Whole. I can dispense with the plug G and With the orifice which it controls. In such oase I discharge the liquid contents from the hollow shank in the same manner as loose granular material, lov simply turning D d Within B b, so as to discharge through the ooinciding openings d b.

I claim as my inventionl. The sample-trier described, having, in combination with the boring-bit A and hollow tubular shank B, With its open side b, the internal close-fitting tube, D, having an open side, d, and means, as the button D', for turning it, all arranged for joint operation as herein specified.

2. In a sample-trier, the plug G, in combination with the boring-bit A, shank B b, handle C, internal tube, D d, and turning means D', for the latter, all arranged to serve substantially as herein specified.
